14 OBSERVATIONS ON TINEINA. 



On the 12th of March I received a letter frora Professor 

 Zeller, with the news that Herr Teich, of Riga, had bred 

 several dozen Cosmoptei'yx Lienujiella from Arundo 

 Phragmites. 



On the 14th of May Professor Zeller w^rote again on the 

 subject, that Herr Biittner had received from Herr Teich of 

 Riga a number of C, Lienigiella, and the latter had pro- 

 mised him the larva in autumn, which feeds in the leaves of 

 reed, ^* like Co7npla?ieUa." 



By this time I had spoken to some of our fen collectors 

 on this new discovery, and they seemed rather incredulous 

 that Liemfjiella should be a reed-feeder ; so I replied to 

 Professor Zeller—" Your notice of Cosmopteryx Lie7iigiella 

 larva makes my mouth water : does it really feed on Arundo 

 Phragmites? " 



To this Professor Zeller replied on the 20th of May—" I 

 believe it is quite correct about the food-plant of Lienigiella ; 

 Herr Biittner has received the insect so freely that he has, 

 unsolicited, given me four specimens. In all probability we 

 shall get the larva this season for figuring ; and, if you wish 

 it, larvae can be sent direct to you, in order that you may 

 personally breed the imago. Please, therefore, to mention 

 whether you wish any larvae sent you, in order that I may 

 attend to them." 



On the 11th of September I heard from Professor Zeller 

 that Dr. Schleich had sought in vain for the larvae of 

 Lienigiella in the locality near Stettin where that species 

 occurs, and that though he had written to Herr Teich at 

 Riga to send him some larvae, he had as yet no reply. 



Four days afterwards, however, I received from Baron 

 V. Nolcken about a dozen larvae of Cosmopteryx Lienigi- 

 ella; they had had a nine days' journey from Arensberg to 

 Lewisham, and all were dead when they arrived !
